Environments
Localities
At the Kintore opencut, Broken Hill South Mine, Broken Hill, Broken Hill district, Yancowinna county, New South
Wales, Australia, gartrellite
occurs on fine-grained quartz -
spessartine rocks associated with
hidalgoite, beudantite,
segnitite,
philipsbornite,
quartz and spessartine
(HOM, AJM 3.1.58, AM 75.932).
The gartrellite appears to preserve rough outlines of crystals of a hexagonal mineral, probably
mimetite, which have been dissolved
(AJM 3.1.58).
At the type locality, Ashburton Downs Station, Ashburton Shire, Western Australia, gartrellite occurs in
an oxidised mineralised shear zone. It is found as segregations in the compact masses of
secondary minerals around
tennantite remnants, and also in veinlets penetrating
tennantite,
sometimes associated with olivenite. Other associated minerals include
quartz, clay minerals,
iron oxides, and numerous
secondary
copper minerals
(AM 75.932, HOM, AJM 13.1.37).
At Falgayrolles, Monteils, Villefranche-de-Rouergue, Aveyron, Occitanie, France, gartrellite has been
found with baryte
(Mindat photo).

At the Tsumeb mine, Tsumeb, Oshikoto Region, Namibia, gartrellite is associated with
mimetite,
duftite, beudantite,
bayldonite and quartz
(HOM)
